胶合竹-GFRP植筋黏结锚固性能试验研究
Experimental research on the bonding and anchorage performance of glued-in GFRP rod in glubam
摘要
Abstract
Fiber reinforced polymer(FRP)rod is a reasonable alternative to steel rod used in glued-in rod engineered bamboo structures,mainly attributed to its significantly higher strength-to-weight ratio and excellent corrosion resistance.However,research in this field is limited.In this study,a total of 60 glued-laminated bamboo(glubam)specimens with glued-in single glass fiber reinforced polymer(GFRP)rod were subjected to axial pull-pull tension tests.The investigation focused on the effects of anchorage length,rod diameter,and bonding length-to-diameter ratio on the anchorage performance.Test results revealed that all specimens failed due to debonding at the glubam-adhesive interface.Approximately 27%of the specimens exhibited pure adhesive failure,while about 70%of specimens experienced a mixed failure mode involving both adhesive pull-out and shear failure in glubam,and 3%of specimens exhibited splitting failure of glubam.Furthermore,the bonding strength of the glued-in glubam joints is primarily governed by the anchorage length or abonding length-diameter ratio of glued-in GFRP rods,corresponding to a negative correlation between them.In contrast,the axial stiffness of the glued-in glubam joints increases with increasing of the diameter of the GFRP rod.Based on the single-parameter correlation analysis,a strength model and an axial stiffness model were proposed for predicting the mechanical performance of glubam joints with glued-in GFRP rod,which also demonstrated good agreement with the experimental data.关键词
